To ensure optimal winding, we recommend setting a watch winder to approx. 800-1000 revolutions per day. Please note the following recommendations for the direction of rotation of the watch winder:
Calibre U 289x and UNG-07.01: both sides.
Calibre 775x, UNG-25.xx and UNG-27.xx: one-sided, counter-clockwise
Hand-wound watches are unsuitable for watch winders.
Please note that even when using a watch winder, wear and tear occurs in the movement and therefore a revision is recommended every 4 to 5 years.
